Upgraded DVR for cameras. Old one had another drive die (went through one every couple years) and was always slightly annoying (crap UI, could no longer connect with windows only app worked, all connected cameras must be same resolution, etc).
New one is a dahua from ali. It is similar to the old one but UI is better, functionality is better (accommodates multiple resolutions, accommodates ip cameras and analog cameras, etc) and it includes AI. I thought the AI would be huey (and maybe it is) but so far it has done a great job identifying vehicles and pedestrians and flagging them for easy review.
